Greg Bender's web site has the rider's manual for the V7 Sport with a description of how to adjust the 4LS brake.

Thanks for the reference, however incomplete. It gets about as far as I decribed, but says nothing about how to set-up the link arm on each side. That's the real trick to making these things work. You can't just assume the original set-up will keep them together. I supose, given enough time in one relationship, they will settle into equalibrium as the tighter pad wears faster than the weak one. I'd like to do a little better...

Syncing front and rear shoes independently on each side is fairly simple since there is little give and take with the arm linkage. Side to side is harder because the cables stretch and bind, and the duplex cable perch tends to tilt in an effort to compensate. I found using the cable stretch as an indicator helped find the center.

Thank goodness I did this on a lift. It would be rough trying to do it on the ground.

just dont expect too much from one of those guzzi 4LS,
even when new they were described as adequate.

now, 40 years later , with all the cars equipped with ABS a drum braked guzzi is pretty lethal.

( i've owned a drum braked V7sport for the last 30 years, in those years i spent more time working on the front drum brake than on the engine)

cheers,

I've had the bike for about five years. This is the third time through on the front brake. I just leave a little more distance. When adjusted, it doesn't bother me much. The bike is kind of a Sunday special.
